Abstract

A medical article, such as a connector fitting, is stabilized on a patient with a retainer having a base and moveable walls. Actuation surfaces configured to move the walls in at least a lateral direction towards each other are suspended above the base by a pair of supports. When pressed together, inner surfaces of the walls form a channel configured to encircle the medical article. The medical article may be pressed down against the actuation surfaces by a medical provider to cause the walls to encircle the medical article. Thereafter, the medical provider may snap the walls together using a latching mechanism to stabilize the medical article on the patient.

Claims

1. A retainer for securing a medical article to a patient, the retainer comprising:

a base;

a plurality of walls supported by the base and forming a channel there between, at least one of the plurality of walls being movable towards another one of the plurality of walls and between an open and closed position, the plurality of walls being configured to press against the base when in the closed position;

an actuation surface configured to move the plurality of walls from at least the open position to the closed position when pressed in a direction towards the base; and

a support having a first end and a second end, the first end being fixed to the base and the second end being attached to at least one of the plurality of walls via a flexible coupling, the flexible coupling being spaced in a lateral direction from the first end.

2. The retainer of claim 1, wherein the flexible coupling connects to the movable wall at a location between transverse ends of the movable wall.

3. The retainer of claim 1, wherein edges of the plurality of walls define an upper opening into the channel, the edges contacting each other when the movable wall is in the closed position.

4. A stabilization system having a first configuration for accepting a medical article and a second configuration for securing a medical article, the system comprising:

an anchor pad having a first surface, at least a portion of the first surface being covered by an adhesive for attachment to a patient'"'"'s skin; and

a retainer supported by the anchor pad, the retainer comprising;

a base,

first and second walls being supported by the base, at least one of the first and second walls being movable in an outward direction with respect to the other wall, wherein each wall comprises an inner surface having an arcuate shape,

an actuation surface disposed between the first and second walls, the actuation surface being configured to cause the first and second walls to encircle an outer circumference of at least a portion of the medical article when the medical article is pressed against the actuation surface, and

first and second supports, at least one of the first and second supports spacing the actuation surface from the base at least when in the first configuration, wherein the first support is attached to the first wall via a first flexible coupling and the second support is attached to the second wall via a second flexible coupling, the first and second couplings being configured to expand or stretch under stress.

5. The stabilization system of claim 4, further comprising latching means disposed on the first and second walls for securing the first and second walls about the medical article.

6. The stabilization system of claim 5, wherein the latching means are engaged by pressing down on an upper surface of the first wall.

7. The stabilization system of claim 4, further comprising a lip formed on the first wall, the lip being configured to snap into a recess formed in the second wall.

8. The stabilization system of claim 4, wherein the second configuration is defined when the first and second walls form an enclosed channel, the retainer being configured to inhibit at least lateral and transverse motion of the medical article placed inside the channel.

9. A retainer having an open configuration and a closed configuration, the retainer comprising:

a pair of receiving surfaces defining a receiving space there between for receiving a medical article when the retainer is in the open configuration, the pair of receiving surfaces contacting at least a portion of the medical article when the retainer is in the closed configuration;

a coupling connected to at least one of the receiving surfaces so as to permit movement of the at least one receiving surface in a direction toward the other receiving surface of the pair of receiving surfaces;

at least one actuation surface coupled to the at least one receiving surface and configured for movement in at least a generally transverse direction, wherein pressing the medical article against the at least one actuation surface when the retainer is in the open configuration moves the at least one receiving surface in a direction toward the other receiving surface of the pair of receiving surfaces; and

a support extending from a base of the retainer, the support connected to a first receiving surface of the pair of receiving surfaces via the coupling, the coupling being configured to expand or stretch under stress.

10. The retainer of claim 9, wherein the medical article comprises a connector fitting, and wherein the receiving space conforms substantially to a cylindrical shape so as to encircle an outer circumference of the connector fitting.

11. The retainer of claim 10, further comprising an abutment surface configured to abut a surface of the connector fitting so as to inhibit motion of the connector fitting in at least one longitudinal direction.

12. The retainer of claim 9, further comprising an upper surface for a medical provider to press, the retainer being snapped into the closed configuration when the at least one actuation surface is depressed and the medical provider presses on the upper surface.

13. The retainer of claim 9, further comprising a base that limits transverse motion of the pair of receiving surfaces when the retainer is in the closed configuration.

14. The retainer of claim 13, further comprising a second support extending from the base, wherein the at least one actuation surface is suspended above the base between the first and second supports.

15. The retainer of claim 14, further comprising a second coupling connecting the other receiving surface to the second support.

16. The retainer of claim 9, wherein the receiving space accepts the medical article from a location above the retainer when the retainer is in the open configuration.

17. The retainer of claim 9, wherein pressing the medical article against the actuation surface when the retainer is in the open configuration moves the other receiving surface of the pair of receiving surfaces in a direction toward the at least one receiving surface.

18. The retainer of claim 9, further comprising a second actuation surface coupled to the other receiving surface of the pair of receiving surfaces, wherein pressing the medical article against the second actuation surface when the retainer is in the open configuration moves the other receiving surface in a direction toward the at least one receiving surface.

19. The retainer of claim 9, wherein each of the receiving surfaces has an arcuate shape.
